Data: Open, big, linked
Open: access…everyone to use and republish as she wishes
Big: scalehigh volume, velocity and variety
Linked: usePublish once, use as many times

Why Open Dataomore & better information o objective and processable
information for economic/political “dialogue”
• to promote competition• to decrease cost • to judge the efficiency of policy
mixtures• to enable participation
24
(initial) scope OGD
to provide an objective & intermediate layer of information that will enable citizens, journalists, business people and politicians to re-discover their own “stories” from data.
25
LOD in Greece: why it is important
• quality of information during economic crisis
• transparency & efficiency in funding development
26
Issues
ohow can we initiate the virtuous cycle of creation?
demonstrate LOD’s added value
ohow to get the most out of data?local & global interconnections
27
In few words,
Apps, Apps, Apps…..
28
Public Spending in Greece & worldwide publicspending.net
• the first LOD App in Greece• daily updates• open spending linked data,
endpoint & visualizations

Insights in Global Public Spending
Open but Effective?
oWho really gets the public money?
oFor what? From whom?oCan we compare them?o Is public spending effective?o<your question goes here>

categories

categories

2. Not uniform Company names

The problem: different
names for the same company
“Oracle” in the Australian public spending
Reconciling Company names: the CORFU technique
Rodríguez, Jose María Álvarez, Ordoñez de Pablos, Patricia, Vafopoulos, Michalis N. and Labra, José Emilio
3. Compatible Payment categories
The problem:
Spending decisions are using different (or not any!) classification schemes (e.g. CPV, UNSSC, NAICS)
38
Compatible Payment categories
Transforming classification schemes or literal descriptions to CPV, expanding:

the 5 stars of open linked data
★make your stuff available on the Web (whatever format)
★★make it available as structured data (e.g. excel instead of image scan of a table)
★★★non-proprietary format (e.g. csv instead of excel)
★★★★use URLs to identify things, so that people can point at your stuff★★★★★link your data to other people’s data to provide context
http://lab.linkeddata.deri.ie/2010/star-scheme-by-example/
Linked data = internet + http +
RDF
Linked Data Principles
1. Use URIs as names for things2. Use URIs so that people can
look up (dereference) those names.
3. When someone looks up a URI, provide useful information.
4. Include links to other URIs so that they can discover more things.
Web as a database
• Linked Data makes the web exploitable as ONE GIANT HUGE GLOBAL DATABASE!
• Is there any query language like sql?SPARQL…
What are we planning?
• LOD for the main economic activities (insurance, banking)
• Law for open data by default in ALL public organisations
• Open data education (open generation)
